200QJ 300QJ Deep Bore Well Submersible Pump, The QJ-type submersible pump is a water lifting machine that integrates directly into the water. It is suitable for extracting groundwater from deep wells and can also be used for water lifting works such as rivers, reservoirs and canals. The submersible pumps are mainly used for Farmland irrigation and mountainous areas of human and animal water, but also for cities, factories, railways, mines, site for water use.

QJ-type submersible pump unit consists of: water pump, submersible motor (including cable), water pipes and control switch composed of four parts. Submersible pump for the single-suction multi-stage vertical centrifugal pump: submersible motor for the closed water-filled wet, vertical three-phase cage asynchronous motor, motor and pump through the claw or single drum coupling directly; equipped with different specifications of the three Core cable; starting equipment for different capacity levels of air switch and self-decompression starter, the water pipe for the different diameter of the steel pipe made of flange connection, high-lift pump with gate control.

Pump Part: At the top of submersible motor pump,the centrifugal pump is connected with motor by rigid shaft coupling.The bearing is water lubricated.The backpressure valve is fixed on the top of the pump to avoid the working parts being damaged by the returned water in pump when the submersible motor pump stops.The water in pump can flow away through the drainage hole in the valve in case the pump is broken in winter.(Note:There is no backpressure valve in low head submersible motor pump).

Motor Part: At the bottom of submersible motor pump,closed water-filled structure,guiding bearing and thrust bearing use water lubricated material.The compensation diaphragm is fixed on the bottom of motor to adjust the differential pressure caused by the ring temperature of motor.The sand-proof structure is fixed on the top of motor to prevent mud and sands to enter inside of motor.

Uses and characteristics:200QJ series submersible pump is a kind of centrifugal water pump with flow range of 10-80m3 / h and lift range of 11-600m. It is mainly used for pumping water from deep wells and reservoirs. It is widely used in farmlandIrrigation, urban industrial and mining enterprises to the drainage and the plateau, mountain water and livestock.With simple structure, easy installation and maintenance, energy efficient and so on.
